function Remove-BoxstarterPackageNugetFeed {
<#
.SYNOPSIS
Removes the Nuget feed associated with an individual package.

.DESCRIPTION
A Chocolatey package repository may publish different packages to 
different feeds. Remove-BoxstarterPackageNugetFeed removes the Nuget 
feed associated with a specified package name. After doing so, the 
package will be associated with the DefaultNugetFeed that can be set 
with Set-BoxstarterDeployOptions and is set to the public Chocolatey 
feed by default. If you do not want any feed to be associated with a 
package, explicitly use Set-BoxstarterPackageNugetFeed to set the 
feed of a package to $null.

.PARAMETER PackageName
The name of a Chocolatey package in the local repository for which the 
feed should be removed.

.Example
Remove-BoxstarterPackageNugetFeed MyPackageName

Removes the Nuget feed associated with MyPackageName
